An orofaciodigital syndrome caused by a mutation in the INTU gene.
Features include always present findings: Decreased body weight, Micropenis, Hearing loss (hearing impairment), and Delayed speech and language development and others.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Brain and nerves | 2 | Delayed speech and language development, Enlarged brain ventricles (ventriculomegaly) |
INTU encodes inturned planar cell polarity protein (942 aa). Plays a key role in ciliogenesis and embryonic development. Highest expression in Ovary (12.0 TPM) and Nerve Tibial (11.8 TPM).
Orofaciodigital syndrome 17 is associated with mutations in the INTU gene on chromosome 4.
INTU is classified as a druggable target (Cell Surface category) with score 52.2.
Genetic testing for INTU is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 23 always present features.
No clinical trials have been registered for orofaciodigital syndrome 17.
